And there is the disconnect between geeks and non geeks, or on a broader term, laymen and non-laymen.
EVEN IF OF THEIR OWN DOING, people are going to construe an app that takes information they themselves provide and use it in such a manner as creepy.
I understand they need to lock down their profile.
But that isnt the point. Its the perception.
There is a staunch difference in the scenario you are depicting and what this app was aimed to do, just as there is a difference in what the app is aimed to do versus what Facebook and Foursquare are aimed to do.
Dont get me wrong, I am not saying the users should not carry most of the blame because they should, and yes, legally they are (the app maker) doing nothing wrong. And im as liberal as they come when it comes to rights
. . . but its still creepy as shit
